M H Ma of the so called reaction type, the principle of operation of my invention in both cases being the same.

In accordance with the provisions of the patent statutes, I have described the principle of operation of my invention together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is only illustrative, and that the invention can be carried outby other means.

What I claim as new, and desire to secure by Letters Patent of the United States, 18

1. The combination with a multi-stage turbine, of a pipe for drawing off steam for heating purposes, andv means responsive to the fluid pressure in said pipe for effecting the withdrawal of steam from one or another of the stages of said turbine.

2. The combination with a multistage turbine, of a pipe for drawing ofl' steam for heating purposes, ports connecting said pipe with several of the stages of said turbine, and a valve means controlling said ports and responsive to variations of fluid pressure in said pipe.

3. The combination with a multi-stage turbine, of a pipe for drawing ofl steam for heating purposes, ports connecting saidpipe with several of the stages of said turbine, a valve controlling said ports, means biasing said valve in one direction, and means for causing the fluid pressure in said heating pipe to force said valve in the opposite direction. I Y '4. The combination with a multi-stage turbine, of. a pipe for drawing ofi steam for heating purposes, ports connecting said pipe with several stages of said turbine, a valve controlling said ports and responsive to variations in fluid pressure in said heating pipe, and means for preventing leakage of steam between stages of the turbine when said valve is in intermediate positions.

5. 'he combination with a multi-stage turbin of a pipe for drawing ofi steam for heating purposes, a casing having ports communicating respectively with several stages of said turbine, a valve in said casing controlling said ports and responsive to variations in fluid pressure in said heating pipe, and outwardly opening check valves controlling said ports. I

6. The combination with a multi-stage turbine, of a pipe for drawing ofi steam for heating purposes, a casing having ports communicating respectively with several stages of said turbine and with the high pressure steam main, and a valve in said casing controlling said ports and responsive to variations of fluid pressure in the heat-ing pipe.

7. The combination with a multi-stage turbine, of a conduit for drawing off steam from different stages for industrial purposes, and a valve means which controls the admission of steam from two or more stages to said conduit, said valve means being arranged to connect a stage of lower pressure to the conduit as the demand for industrial steam decreases and to connect a stage of high pressure to said conduit as the demand increases.

8. The combination with ya multi-stage turbine, of a conduit for drawing of! steam from different stages for industrial purposes, a valve means'which controls the admission of steam from two or more stages to said conduit, said valve means being arranged to connect a stage of lower pressure to the conduit as the demand for industrial steam decreases and to connect a stage of high pressure to said conduit as the demand increases, and pressure responsive means for adjusting the 9. The com ination with a turbine in which the pressure decreases from point to point therein, a conduit supplying steam for industrial purposes, a plurality of ports osition of the valve means.
